Every once in a while we will seed with "Blue Ribbon" (4-way Kentucky bluegrass). And very rarely we seed with fine fescue. Main reason is to exactly match "certain" lawns.
But I'm guessing over 98% of our seeding jobs = a 4-way blend of TTTF (turf-type tall fescue). It's the "new wave" in grass seed. ISU seeded over 100 TTTF cultivars in test plots at their research farm 2 years ago. ISU's 2 top turfgrass experts even have TTTF in their home lawns.
TTTT was initially suggested to me by a good friend in KS. (grassman). Followed up shortly after that by Iowa State University. Now I swear by it, and most customers are very pleased with it.

I am thinking of using more and more TTTF for overseeding, and less KBG.
